Although it may sound strange judging by the way you say you feel, the social aspect to your life is entirely within your hands. Use the search function (magnifying glass at upper right) and put in your favorite desired term. You will see that there have been many fields created that have changed the paradigm of your fellow forum members.
If the mandala above did not help, I guarantee it was still doing its job. Something happened from the time you were a social person to the time you apparently had no one to share your life with. What was that? If you are no longer the same person, it might be really a good thing that your old friends are no longer around. Rather than turn the energy on yourself, add love and gratitude for life and be a beacon that will draw others to you. Just by posting here you have drawn some, yes?
There is so much here to enjoy and learn and I encourage you to dive into the big pool of knowledge and goodies that is our Sapienmed forum.
I have recently found the Social Bonding audio to be a real help. Check it out here.
And have fun with us!
